So i have a OEM built PC and it came with a 32 bit version of Windows 7 home premium. today i installed windows 7 home premium 64 bit and everything went smootly untill i tried to upgrade to windows 10 and it asked for my activation key, So i looked at the
side of my pc and it said COA product key. So i put in my product key and it said invalid key i tried this multiple times, But it didn't work does my 32 bit key not work on 64bit windows? or is there something wrong with my key?
